3. Configuration

3.1. Operation Modes

In addition to the serial port configurations such as bit/second, data bit, parity, stop bit, flow control,
Parani-SD has some configurations for Bluetooth. For getting the most out of Parani-SD, user should
understand the following Bluetooth connection schemes.

A Bluetooth device can play a role as a master or slave. Master tries to connect itself to other
Bluetooth device, and slave is waiting to be connected from other Bluetooth devices. A Bluetooth
connection is always made by a pair of master and slave. A slave can be in two modes, Inquiry Scan
or Page Scan mode. Inquiry Scan mode is waiting the packet of inquiry from other Bluetooth devices
and Page Scan mode is waiting the packet of connection from other Bluetooth devices. Every
Bluetooth device has its unique address, called BD (Bluetooth Device) address, which is composed of
12 hexa-decimal numbers.

Parani-SD has 4 operation modes as follows. Each mode can be identified with LED indicators as
illustrated in next section.

Table 3-1 The Parani-SD Operation Modes

Mode Description
Mode0

Mode1

Mode2

Mode3

Parani-SD must be in Mode0, when it is directly controlled by AT commands.
In this mode, there is no response when power on or software reset, and Parani-SD is just
waiting for AT command input. Neither master nor slave is assigned to Parani-SD in mode0.
User can change the configurations of Parani-SD in this mode.
The factory default is set to Mode0.

Parani-SD tries to connect the last connected Bluetooth device.
Parani-SD in Mode1 is to be a master and tries to connect the last connected Bluetooth
device. Parani-SD always stores the BD address of the Bluetooth device to which Parani-SD
has connected last time. When Parani-SD is initially used or after hardware reset, there is no
BD address stored in Parani-SD. In this case, Mode1 does not make any sense and mode
change from other operation modes to Mode1 is not allowed. The mode change to Mode1 can
be made after Parani-SD succeeds to connect to other Bluetooth device in Mode0. Once
changed to Mode1, Parani-SD will try to connect automatically the last connected Bluetooth
device whenever power on or software reset.
Parani-SD in Mode1 cannot be discovered or connected by other Bluetoot h devices.

Parani-SD is waiting for the connection from the last connected Bluetooth device.
Parani-SD in Mode2 is to be a slave and waiting for the connection only from the last
connected Bluetooth device. Just like Mode1, if there is no BD address stored in Parani-SD,
the mode change from other operation modes to Mode2 is not allowed. Once changed to
Mode2, Parani-SD will wait for the connection from the last connected Bluetooth device
whenever power on or software reset.
Parani-SD in Mode2 cannot be discovered or connected to Bluetooth devices other than the
last connected device.

Parani-SD is waiting for the connection from any other Bluetooth devices.
Parani-SD in Mode3 acts like in Mode2, but allows any connection from other Bluetooth
device. Most of general Bluetooth device is set to Mode3.
Parani-SD in Mode3 can be discovered and connected from any other Bluetooth devices.

3.3.1. Data Bit

Parani-SD supports only 8 data bit. In the case of 7 data bit, please contact the technical support.

3.3.2. Hardware Flow Control

Parani-SD plugged into its host system transmits data from host to the other side Bluetooth device.
These data is saved temporarily in the internal buffer of Parani-SD and sent repeatedly until the
transmission is completed packet by packet. When the radio transmission condition is not good
enough to send data promptly, it can cause the transmission delay. If the host sends more data when
the buffer is full, buffer overflow will make Parani-SD malfunction consequently. In order to prevent this
buffer overflow, Parani-SD works as follows.

11

In case of using hardware flow control, Parani-SD makes RTS be ‘disable’ to stop receiving further
data from the host when the buffer becomes full. RTS will be ‘able’ to begin receiving data again from
the host when the buffer has some room for more data.

In case of not using hardware flow control, Parani-SD clears the buffer to secure the room for next
data when the buffer becomes full. This means the loss of data. As the transmission data becomes
large, the possibility of data loss goes higher.

For large data transmission, use of hardware flow control is highly recommended.

3.3.3. Reset to Factory Defaults

To turn back all the configurations to its factory settings, press the reset button depicted in Fig. 1-3.
Press the reset button with a narrow pointed tool like paper clip longer than 1 second. Reset works
only when power is on.

3.3.4. Dipswitch

This feature is only on Parani-SD205. With the combination of 4 slot dipswitches, baud rate and
hardware flow control can be set simply without host computer.

Upper 3 dipswitches are used for setting baud rate, and bottom dipswitch is used for setting hardware
flow control option. If the baud rate needs to be set out of the range given below, ParaniWIN or
terminal program should be used for extended AT commands. At this time combination of dipswitches
must be complied with AT cmd. Then baud rate will go back to 9600 as default.

3.3.5. Pairing Button

Parani-SD provides Pairing Button for instant configuration without PC to make an automatic
connection between two Parani-SDs. For convenience sake, name two Parani-SDs as SD1 and SD2
respectively.

Step 1. Turn off all the nearby Parani-SD
Step 2. Turn on SD1 and SD2 and hardware reset both of them by pressing Reset Button.
Step 3. Press the Pairing Button of SD1 for 2 seconds until Standby LED turns off and Connect LED

blinks 3 times every 2 seconds. Keep the power ON.

Step 4. Press the Pairing Button of SD2 for 2 seconds until Standby LED turns off and Connect LED

blinks 3 times every 2 seconds. Now press again the Pairing Button for 2 seconds until Connect
LED blinks every 0.5 second.

Step 5. Wait for SD1 & SD2 to be connected for a while until Connect LED’s of SD1 and SD2 is lit in

green. It takes about 10 seconds to make a connection. If there are many Bluetooth devices nearby,
it will take a little bit more.

Step 6. Turn SD1 off and on. Connect LED blinks twice in green every 3 seconds.
Step 7. Turn SD2 off and on. Connect LED blinks once in green every 1 second.
Step 8. Now a pair of Parani-SD is configured to make automatic connection, whenever power off and

on.
Just use this pair of Parani-SD like virtual serial cable.

* Note: While pairing is progressing by the pairing buttons, the Command Response will be inactivated
automatically. Then, Parani-SD will not send the response messages such as OK, Connect and
Disconnect.

Serial port settings can be changed by <Start Configuration> and <ParaniWIN Configuration> of
ParaniWIN in the menu bar at upper left corner of the window without re-running the ParaniWIN
program.

Figure 3-6 Menu Bar at Upper Left corner of ParaniWIN

The icons in the left side window come to the corresponding windows.
In device configuration window, hardware reset can be executed or operation mode and RS232 can

be configured as well. Security option also can be configured in this window.

Figure 3-7 Device Setting Window

Parani-SD supports two security options, Authentication and Encryption. If you check the
Authentication option, you must also enter the Pin Code value. If the authentication is activated, the
connection, only between the Master and Slave device that share the same Pin Code, is established.
In case that Parani-SD connects to other Bluetooth device that enables authentication, you must know
the other device’s Pin Code. In general Bluetooth devices, 1234 or 0000 is used as a default value. If
you check Encryption option, the Parani-SD encrypts packets and sends them. The Encryption options
works well in case that only one between Master and Slave uses this option.

16

Parani-SD has 4 response messages, ‘OK’, ‘ERROR’, ‘CONNECT’, and ‘DISCONNECT’. In some
cases, these responses can affect the host system unexpectedly. To prevent this, user can set the
Command response to ON or OFF.

For Parani-SD100L/200, hardware flow control can be configured only by dip switch. Thus H/W Flow
Control option will not work in this case. When the dipswitch value isn’t ATcommand mode, the RS-232

menu will be disabled.

Click [Apply] button to reflect the given options to Parani-SD actually.
Connect(out) icon will show the following window to search and connect other Bluetooth devices.

Figure 3-8 Connect(out) Window

Click [Search] button to search nearby Bluetooth devices. The maximum number of devices to be
searched can be controlled. Select one of the devices searched and click [Connect] button. The
selected Bluetooth device must be in Page scan mode. Click [Disconnect] button to cancel the
connection normally.

After the connection is established, you are able to test sensitivity by pushing the START button.

17

Figure 3-9 Sensitivity Test

The sensitivity test shows LInkQuality and RSSI values. The sensitivity is fine, If the LinkQuality is
closer to 255 and RSSI is closer to 0. In general, the sensitivity is the best when the distance is 10
meters. You can push the STOP button in order to terminate the sensitivity test. The sensitivity test will
continue until the STOP button is pushed. If you close the ParaniWIN Window without pushing the
STOP button, you must restart Parani-SD to terminate the test.

Connection(in) icon will show the following window to make Parani-SD wait to a connection from the
other Bluetooth device. The waiting time in seconds can be controlled. With 0 input for this waiting
time, Parani-SD keeps waiting for connection until [Cancel] button is clicked.

18

Figure 3-10 Connection(in) Window

If the Connection Wizard icon is clicked, an easy pairing menu to use appears as follows:

Figure 3-11 Connection Wizard Window

19

This menu make easy pairing configuration of Parani-ESD that hasn’t pairing button. Although this
menu can be used to pairing configuration of Parani-SD that has pairing button, pairing configuration
by pairing button is recommended. To use this menu, follow next steps.

Step 1. Connect the first SD and then push the START button.
Step 2. Disconnect the first SD, connect the second ESD and then push the Next button after setting

up Slave configuration. At this time, the dip switch value should be ATcommand mode. The flow

control setting can be changed only through dip switch.
Step 3. Disconnect the second SD, once again connect the first ESD and then push the Finish button.

The pairing configuration finished. Make sure that each SD’s connect LED is on. From now, when

In ‘Connect’ status, data from host is transmitted to the other side Bluetooth device, and

any AT command is not accepted but this command, which is not echoed on the screen.
When Parani-SD encounters a character ‘+’ from host, it stops the data transmission and
waits for next 2 characters. If the next 2 characters aren’t both ‘+’, it restart to transmit data
including the first ‘+’ as well. If not, it converts the operation status to ‘Standby’.
If the data from host includes ‘+++’, it will convert the operation status to ‘Standby’
unexpectedly. Notice that Parani-SD holds data transmission when it encounters ‘+’, until

Appendix C: S-Register

S-registers contain 46 parameters of Parani-SD. These are stored in flash memory and sustained the
values unless hardware reset is executed. The value of S-register can be accessed and changed with
ATS command by user. Some S-registers not shown below are set to maximize the performance of
Parani-SD. Thus it is not recommended to change these S-registers.
Change the value of S-register only in Standby status.

C.1. S1: Force to Reconnect (default 1)

S1=0, Parani-SD in Mode1 does not try reconnection when disconn ected.
S1=1, Parani-SD in Mode1 keeps trying reconnection when disconnected.

C.2. S2: Enable Hardware Flow Control (default 1)

S2=0, Parani-SD’s hardware flow control is off.
S2=1, Parani-SD’s hardware flow control is on.

In case of SD Series, it can be changed only through dip switch.

C.3. S3: Stream UART Policy (default 0)

S3=0, the priority of UART streaming is throughput.
S3=1, the priority is latency, which minimizes the delay of data transmission. This is useful in case of

transmiting very small data quickly.

This value decides the way of handling stream data from UART. When this value is 1, in order that SD
minimizes the latency, SD sends the received data immediately. When this value is 0, in order that SD
maximizes throughput, SD stores received data for a short time and sends a large packet. If the
packet length is less than100 bytes, latency-oriented way is better. But if the packet length is more
than 100 bytes, throughput-oriented way is recommended. Also if you want to use high baudrate,
throughput-oriented way is more effective. Just for reference, the buffer length for receiving is 2 Kbytes.

C.4. S4: Enable Remote Name Query (default 1)

S4=0, Parani-SD inquires only BD address. This speeds up the inquiry process.
S4=1, Parani-SD inquire BD address, device name and class of device.

This value decides whether SD finds friendly name of Bluetooth device or not. When this value is 1,
SD finds not only BD address but also friendly name. When this value is 0, SD finds only BD address.
Without finding friendly name, a searching is quick to respond. If you want to search the other
Bluetooth devices quickly, set this value to 0. In case of using pairing button, finding friendly name will
be omitted automatically.

C.5. S6: Enable Low Power Mode (default 0)

S10=0, deactivate Low Power Mode.
S10=1, activate Low Power Mode.
This value decides whether SD works in Low Power Mode or not. When this value is 0, SD works only
in active power mode. When SD works in Low Power mode, delay in transferring data may occur.

C.6. S10: Enable SD Response (default 1)

S10=0, Parani-SD does not send SD responses to host system.
S10=1, Parani-SD send SD responses to host system.

This value decides whether SD sends response messages such as OK, ERROR, CONNECT,
DISCONNECT or not. When this value is 0, SD sends no response messages. If the response
messages cause troubles in host programs or devices that is connected to SD, change this value to 0.

C.7. S11: Enable Escape (default 1)

S11=0, Parani-SD does not allow escape sequence character. The operation status of Connect cannot

be changed to Standby. As Parani-SD skips the process detecting escape sequence character, the

more efficient data transmission is expected.
S11=1, Parani-SD allow escape sequence character. Whenever it is needed, the Connect status can

be changed to Standby.

C.8. S12: Clear Data Buffer When Disconnected (default 0)

S12=0, Parani-SD does not clear the data buffer received from host system when disconnected.
S12=1, Parani-SD clears the data buff er when disconnected.

C.9. S14: Enable DTR Transfer (default 1)

S14=0, DTR/DSR signal is transferred to loop-back.
S14=1, DTR signal is transferred to DSR of remote device.

C.10. S15: Enable Disconnect by DTR (default 0)

S15=0, DTR signal cannot release the connection.
S15=1, The Bluetooth connection can be released when DTR signal is off.

This value decides whether Bluetooth connection is released when DTR signal drops or not. If this
value is 1, you can use DTR signal in order to disconnect Bluetooth connection.

C.11. S22: Fast Connect (default 0)

S22=0, none
S22=1, page scan
S22=2, inquiry scan

39

S22=3, page/inquiry scan

C.12. S24: Maximum Number of Inquiry Result (default 10)

The maximum number of inquiry list can be controlled. This value is up to 15,

C.13. S28: Escape Sequence Character (default 43)

The decimal number of the ASCII code of escape sequence character can be controlled. The initial

value is 43, the ASCII code of ‘+’.

C.14. S31: Page Timeout (default 300)

This is the timeout in seconds to attempt connection with ATD command. After this timeout expires, the

SD will restart automatically. If this value is 0, SD will attempt to connect without restarting

C.15. S33: Inquiry Timeout (default 30)

This is the timeout in seconds to execute inquiry scan.

C.16. S37: Supervision Timeout (default 16000)

This is the timeout in 625µsec to presume disconnection, which is set to 16000 initially.
16000¯625µsec=10sec)
The smaller the value becomes, the more quickly Parani-SD can detect an abnormal disconnection.
But when the communication is suspended for some environmental reasons, it may be regarded as
disconnection.

C.17. S46: BD Address of Last Connected Device

This saves the BD address of the Bluetooth device connected most recently.

Appendix D: Trouble Shooting

D.1 No Data Transmission

D.1.1 COM Port Settings

Check whether the Baud rate of Parani-SD is same as that of its host equipment. You can know the

Baud Rare if you check the dipswitch. If it is Atcommand mode, you can initialize Baud rate to 9600 by
pressing Reset Button.

Check whether the Data bit is set to 8. Parani-SD supports only 8 Data bit. If your host equipment
uses 7 Data bit and even or odd parity, it can work as if it uses 8 Data bit and No parity. This is valid
only when both DCE devices are Parani-SD. In this case, set both Parani-SDs to 8 Data bit and No
parity. If one of DCE devices is other Bluetooth device such as Bluetooth USB dongle, please contact
Technical Support.
Check whether the Parity and Stop bit of Parani-SD are same as those of its host equipment. Parani­SD supports No parity, Even parity and Odd parity, 1 and 2 Stop bit.
Check whether the host equipment of Parani-SD uses Hardware Flow Control. Parani-SD is initially
set to Use of Hardware Flow Control. If your host equipment does not use Hardware Flow Control, set
the Hardware Flow Control of Parani-SD to No use. The Hardware Flow Control can be changed only

by dipswitch.

Parani-SD does not support RS-232 break signal.

D.1.2 Pin Assignment

Parani-SD is DCE device. If your host equipment is DTE, plug Parani-SD directly to the host
equipment or use straight RS-232 cable. If your host equipment is DCE, use cross over RS-232 cable
(Null modem cable).

D.2 Data Loss or Malfunctioning

D.2.1Hardware Flow Control

When transmitting large data with No use of Hardware Flow Control, Parani-SD will clear the data
buffer unexpectedly. This possibility goes higher as the RF transmission environment is bad.

D.2.2 A T Response

41

The messages of AT response may affect the function of host system. Set ATS10=0 not to send SD
response to host system and try again. Refer Appendix B. for details.

D.3 Transmission Delay

D.3.1 RF Processing Delay

It takes 30msec approximately for a Parani-SD to complete the data transmission to the other side
Bluetooth device. This time delay cannot be reduced and would be bigger as the RF transmission
environment is bad. Do not use Parani-SD If your applications cannot allow this time delay.

D.3.2 RF Transmission Environment

If there are lots of Bluetooth device working in a small area and/or the RF communication distance is
too long and/or there are some obstacles affecting RF performance, Parani-SD repeats the
transmission packet by packet due to interferences and/or low RF performance. This leads the
transmission time delay.
